Upgrading My DMZ Router for Better Performance
My homelab has a dedicated DMZ network (192.168.4.0/24) that’s physically separated from my main LAN. The only machine currently on this network is minis, a Fedora workstation that also serves as a Kubernetes node for DMZ-facing workloads. I’ve been running a basic router on this segment, but I picked up a faster unit and wanted to document the before/after performance difference.
